CrofAI served 23 of its 26 AI models with a cheaper one

CrofAI, a discount service that resells access to AI models, told users there was a literal zero percent chance its traffic reached OpenRouter. A developer publishing under kendell.dev spent two days from September 12, 2026 testing the catalogue model by model and found 23 of the 26 models checked answered with a different, cheaper model, carrying OpenRouter response IDs. CrofAI denied the finding at 1:52 AM on September 14, admitted three models one minute later and five more within ten minutes. The investigation logged both crof.ai and its beta domain still routing afterwards.
